Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)

Ffmpeg Showfreqs with Custom Frequency Ranges, Is It Possible ?
17 février 2023, par lonewolvianI need to display showfreqs with 32 or 64 bands, but with custom frequency ranges, just like an old equalizer indicator.


In this case, win_size is not what I want because the frequency distribution doesn't look balanced where the treble section is too wide and the bass section is to narrow.


Is it possible ? If so then how to do it ?


I've looked at showfreqs documentation but I didn't find any clue about this.


Thank you.

Script error logging and filtering leads to truncated inputs [duplicate]
11 septembre 2023, par Alex IxerasI have a short script to log the output of an
ffmpegerror output. I want to suppress logging a particular error message, but log any other.

while IFS= read -r file; do
 if [[ "$file" == *.mov ]]; then
 error=$(ffmpeg -v error -i "$file" -f null - 2>&1)
 if [[ "$error" != *"Application provided invalid, non monotonically increasing dts"* ]]; then
 echo "File: $file" >> error.log
 echo "$error" >> error.log
 echo "\n" >> error.log
 fi
 fi
done < /dir/to/list_of_files.txt


On running this I get some output working well, some other however, seems to be truncated or seemingly providing truncated input. Below is some sample output.


There are two truncated inputs (
mes/bar/media/040F4F7F-7555-42C0-A8BE-F00C2240B1E9.movandolumes/bar/media/05DD1E0E-3AA6-4803-9FE3-95101CF69AC7.mov) and one .heic file, which is sitting in the same folder, seemingly causing an issue (r/media/06D46531-B088-46D6-AEEA-7192845D09E0.heic). None of the files and their paths listed in/dir/to/list_of_files.txtis listed incomplete, meaninglist_of_files.txtshows

When I try running the commands individually line by line from the input file, they all work as expected, e.g.


- 

ffmpeg -v error -i "/Volumes/bar/media/006BE123-DA3F-46AA-A7DB-4FB747ECE3A8.mov" -f null -ffmpeg -v error -i "/Volumes/bar/media/026B2681-840E-4B5E-945B-3CD485C74DA4.mov" -f null -ffmpeg -v error -i "/Volumes/bar/media/040C2C65-7643-4432-9C73-3B4A74861908.mov" -f null -ffmpeg -v error -i "/Volumes/bar/media/040F4F7F-7555-42C0-A8BE-F00C2240B1E9.mov" -f null -ffmpeg -v error -i "/Volumes/bar/media/042561B3-A732-457D-8ED4-A81A9EB3A5A7.mov" -f null -ffmpeg -v error -i "/Volumes/bar/media/05DD1E0E-3AA6-4803-9FE3-95101CF69AC7.mov" -f null -














I've also tried initialising the
errorvariable after every output, but without any success.

I'm running this under macOS 13.5 using ffmpeg version 6.0.


Why is the log output truncated or why does this script use truncated input ? Or, where does the script fail leading to these errors ?

Is it possible to "stretch" audio in the frequency domain ?
9 juillet 2024, par Christian SchmitzWe would like to make quite similar frequencies better decernible for further AI-analysis. Because of that, we would like to stretch the audio in the frequency domain. This means that instead of having two frequency bands of 30Hz and 40Hz, is it possible to "stretch" them to have maybe 28Hz and 45Hz ?


Thanks a lot and if that wasn't clear enough, please don't hesitate to ask ! :)


We tried cleaning the data with ffmpeg, but it appears that for our task we need a clearer representation of the frequencies in the data
